CONFIG_PIN_TLB: Pinned Kernel TLBs

General informations

The Linux kernel configuration item CONFIG_PIN_TLB has multiple definitions:

Pinned Kernel TLBs found in arch/powerpc/platforms/8xx/Kconfig

The configuration item CONFIG_PIN_TLB:

• prompt: Pinned Kernel TLBs
• type: bool
• depends on: CONFIG_ADVANCED_OPTIONS
• defined in arch/powerpc/platforms/8xx/Kconfig
• found in Linux kernels: 5.8–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

On the 8xx, we have 32 instruction TLBs and 32 data TLBs. In each table 4 TLBs can be pinned.

It reduces the amount of usable TLBs to 28 (ie by 12%). That's the reason why we make it selectable.

This option does nothing, it just activate the selection of what to pin.
